Java: help comparing unusual character windows/linux

[lozina]

we make a call to a web service which returns XML data. In this data there is sometimes a special character (¤) which we need to be able to look for. In windows I can just say something like indexOf("¤") and it works fine. But this does not work in linux.

any idea how I would go about matching this character reliably in both windows and linux?

Parsing an XML message using string ops is just a bad idea. Stick to JAXP.

 

[lozina]

it makes no diff. the special character is there no matter what we parse it with. its part of the data

 

[HigherGround]

what's the unicode seq for that character? can you find it in a stream when you tcpdump eth on a client side?

 

[lozina]

it's unicode is \u2021 and if I search for that in Windows it works but in linux it does not. Even though it is a single character in linux if I output it to logs it is printed out as 3 bizarre characters together.

edit: sorry for the confusion- I'm referring now to this char: ?, not the same as the one I was dealing with the other day. There are a couple more chars like that. in linux they turn into other characters. like the ? becomes equivalent to a ¥

i think i got it now.

thanks

What did you do to get it working?

 

[lozina]

I don't really understand why it worked, but what I did was I got the byte value of the character and then I just made a string like this:

String crossChar = new String(new byte[] { (byte)-121 });

that for example, is for the ? character

Now when I compare a string looking for that string it finds it both in linux and windows.

This did not work in linux: str.indexOf("?");
but this does: str.indexOf(crossChar);
and still works in windows too.

no idea why it works and why the old way didnt.

It's possible it's some interaction with your locale setting on Linux that's throwing it off.

that was my first thought
